To get close to 500 rwhp, you will need a big cam, ported or aftermarket heads, underdrive pulley, ported throttle body and or intake manifold, and of course headers, cold air kit and tune. Or you can go FI or spray.

Ok how much would it cost to get to lets say 454RWHP also where is a good place to get a loan for performace? To be honest I am gonna use it for cruzie, show, show drag at the strip. it is in storage for the winter so its not my daily driver at all...

I think a more modest goal would fit you best, to start with. A good cam, cold air intake, headers, maybe pulley will get you 460 rwhp easy. That way, you save money on ported heads and manifold. You can always add those later when you want to squeeze out some more ponies.

But for your shop, ask for: cam (and supporting valvetrain, if needed), good headers, and a good CAI (and ported throttle body since it's cheap and people like it). I figure you'd be in for $3k for +80-100rwhp. Heads/manifold may cost you another $2k for maybe another +20rwhp.

Point is, you can have a beast for about $3k with room to grow when you get the itch.
